A Staten Island “anti-aging” doctor on trial for allegedly writing hundreds of illegal steroid prescriptions failed to warn patients of the dangers — leading a man’s two young daughters to grow hair on their legs, prosecutors said yesterday.

Lucente also allegedly gave Joseph Baglio dose upon dose of steroids despite his recent heart transplant. Baglio died, but Lucente has not been charged with causing his death.

Lucente worked out of two Staten Island “anti-aging” clinics, but referred musclemen wannabes — including city cops — to Lowen’s Compounding Pharmacy in Bay Ridge, Brooklyn. Pharmacy co-owner John Rossi shot himself to death in 2008 as the investigation unfolded.

Spanakos said patients paid $1,000 the first year and $400 each year thereafter. Lucente says he was treating hormonal imbalances.
